# Replaces the container: directive so we can free disk space first.
# Uses "docker run -d ... sleep infinity" + "docker exec" to preserve
# installed packages and env vars across steps.
# Retry the pull: nvcr.io intermittently times out ("context deadline
# exceeded") under load, and ~30 matrix jobs hit it at once. Pulls
# resume completed layers, so retries are cheap.
